but nothing came up on the right hand side
Hmmm... Sorry about that.
Turns out problem was on my side. I didn't want to use the precompiled dtc binary in the repo, so I removed it and just used the Debian packaged dtc which didn't work. Building mainline dtc and using that worked a treat.
I really like the tool. I think it is very useful. I'd be happy to host it somewhere under github/devicetree_org, but alternately it could be included in the main dtc repo which will give the tool wider reach.
Cheers, g.
There are these 2 commands that the dtv-demo executes behind the scenes to gather the necessary information. One (or both) of them could be failing. Here is a patch that logs those 2 complete commands with the actual arguments.
Try re-running dtv-demo with this patch applied. Once you have these 2 logs (say cmdX and cmdY), you can try manually running them by piping the output of the first command to the second i.e. cmdX | cmdY to identify and fix whatever is necessary on the system.
If you find that you are having issues running the pre-compiled dtc binary within dtv-demo, please feel free to replace it with any recent dtc binary on your system which supports the -T cmd-line parameter.
